First add 15 to both sides:
2n = 68
Then divide each side by two.
n = 34
I know that because my 8th grade math teacher taught us (in 1954)
that when you see the word "of" in a math problem, it almost always
means "times". So part of your question says "... finding a fractional
part times a whole number ...".
Answer:
A variable which can can be represented in numbers is known to be a quantitative variable.
Step-by-step explanation:
A variable is described as a characteristic of an object. Their values may occur more than once for a set of data.
A variable that can be represented in numbers is known to be a quantitative variable. Arithmetic operations can also be performed on these variables i.e. after performing arithmetic operations such as addition, subtraction, multiplication or division, some numbers can still be obtained as the result.
Quantitative variables can also be compared with each other to obtain meaningful results. Quantitative variables are of two types – discrete and continuous.
Discrete variables have whole numbers as their values whereas continuous variables can even have values in between the whole numbers.
Examples of quantitative variables are height, weight, time in the 100-yard dash, the number of items sold to a shopper.
The answer should be A. a decrease in the availability of food resources, and C. conditions that limit the availability of shelter resources, if there are two correct answer choices.
